Subject: feat(thunderbird): track non-private config in dotfiles

Mirror the firefox/ pattern for Thunderbird:

- thunderbird/user.js: telemetry off, safe-browsing off, remote images
  blocked, read receipts disabled, plain-text compose with flowed
  wrap at 72, vertical pane, calendar on Monday start
- run_onchange_after_deploy-thunderbird.sh.tmpl: detects default
  profile and copies tracked files in on any change
- meta/mail.txt: add thunderbird package (official repo)
- .chezmoiignore: exclude thunderbird/ from $HOME deployment
- README: mention Thunderbird + Bridge + Radicale stack

Accounts/credentials/mailbox data stay local per profile.
